Predictive Energy-Efficient Multicast for Large-Scale Mobile Ad Hoc Networks

by Jung-chun Kao, Radu Marculescu
"... Abstract—Energy-efficient multicast routing is of primary concern for mobile ad hoc networks (MANET). However, none of existing energy-efficient multicast algorithms is applicable to large-scale MANETs, either due to their complexity (which is either NP-hard or polynomial with respect to the network ..."

Energy-efficient wireless network design

by Ioannis Caragiannis, Christos Kaklamanis, Panagiotis Kanellopoulos - Theor. Comp. Sys , 2006
"... Abstract. A crucial issue in ad hoc wireless networks is to efficiently support communication patterns that are typical in traditional (wired) networks. These include broadcasting, multicasting, and gossiping (all-to-all communication). Since, in ad hoc networks energy is a scarce re-source, the imp ..."

Energy-Efficient, Secure Group Key Agreement for Ad Hoc Networks

by Thomas R. Halford, Thomas A. Courtade, Keith M. Chugg
"... Abstract—Public key cryptography is well-suited to ad hoc networks as it requires no a priori secure key distribution mechanism. Recent advances in lattice-based cryptography are enabling the use of public key algorithms (PKAs) in low-power devices. Unfortunately, while many ad hoc networking applic ..."
Abstract - Cited by 1 (1 self) - Add to MetaCart
applications are dominated by multicast traffic, PKAs are inherently unicast: public/private key pairs are generated by data destinations. To fully realize public key cryptography in ad hoc networks, lowpower PKAs must therefore be augmented with energy-efficient mechanisms for secure group key establishment

Cross-layer design for energy-efficient secure multicast communications in ad hoc networks

by Loukas Lazos, Radha Poovendran - In Proceedings of the IEEE International Conference on Communications (ICC , 2004
"... Abstract — We consider the problem of secure multicast in an energy-constrained wireless environment. We present an analytical formulation of the energy expenditure associated with the communi-cation overhead of key management and highlight its dependence on the network topology and the key distribu ..."

We show that the optimal solution of this formulation does not scale with multicast group size and propose a sub-optimal, cross-layer, low-complexity algorithm for energy efficient key distribution. We present simulation studies that show the energy savings achieved by our scheme
